Agressividade infantil: análises de artigos científicos

This project has its topic on child aggression. Child aggression has always been present in the school environment. Therefore, aggressive behaviors have been interpreted as violence in which the educators have come to complaining earlier now. This study has its objective to survey published articles in electronic magazines, which talk about thematic aggression, child aggression and to systemize and analyze these procedures. Therefore, there will be a survey on the articles about this set of themes based on the data from Scielo (Scientific Electronic Library Online). In this data base, there are indexed published articles in electronic magazines from different areas of knowledge considered relevant. The articles will be identified by the keywords of aggressiveness, children, aggression, childhood, infantile, schools and their combinations

Influência da violência no esporte sobre espectadores de MMA: análise de percepções e comportamentos

Modern society lives daily with groups of human beings who have high rates of aggression and violence. Scholars in the field point to the influence of certain environmental condition for the development of aggressive behavior. Among such circumstances, we can quote various aspects including the influence of media, and more specifically, the MMA (Mixed Martial Arts). The MMA is now one of the world's most popular sport, having international visibility through your largest organization, the UFC® (Ultimate Fighting Championship). The sport's global coverage is surely source of influence for our children and adolescents, who without the correct direction, can take the scenes seen in the sport as common facts of everyday life, making aggression and violence acceptable behaviors in their lives. Many studies show behavioral changes related to violent practices in virtue of exposure of individuals to aggression scenes by media. Works provide some interesting theoretical models to explain the observational learning. Under such aspects, the determined reality brings a need for in-depth studies on the subject addressed, looking for a better understanding of relations between the sport's violence and your influences on social behavior of individuals in this context, and then, look for possible solutions to deal with the problem pre supposed

Soporte social, familiar y autoconcepto: relación entre los constructos

This study aimed at verifying the associations between social support, family support and self-concept in a group of men and women. In the male group there were negative correlations between family support and the factors negligence, aggression and indifference of the instrument of self-concept. In the female group, the total family support was positively correlated with sensuality and accountability, and negatively with uncertainty, and these three measures of the instrument of self-concept. The observed relationships between family support and social support were positive, for both men and women.

Witnessing reconciliation reduces arousal of bystanders in a baboon group (Papio hamadryas hamadryas)

Reconciliation is the occurrence of friendly behaviour between opponents shortly after an aggressive conflict. In primate groups, reconciliation reduces aggression and post-conflict arousal. Aggression within a group can also increase arousal of bystanders (e.g. increase bystanders’ rates of self-directed behaviour). Since reconciliation reduces aggression between opponents, we tested whether it also reduces self-directed behaviour in bystanders. Following aggression in a captive group of hamadryas baboons, one observer conducted a focal sample on one of the combatants to document reconciliation and a second observer simultaneously conducted a focal sample on a randomly selected bystander. Matched control observations were then collected on the same individuals in a nonaggressive context to obtain baseline levels of behaviour. The self-directed behaviour of bystanders was elevated after witnessing a fight compared to baseline levels. If combatants reconciled aggression, bystander rates of self-directed behaviour significantly decreased. If combatants did not reconcile aggression, bystander rates of self-directed behaviour remained at elevated levels, significantly higher than after reconciliation. If combatants affiliated with partners other than their original opponent, bystander rates of self-directed behaviour did not decrease. The rate of bystander self-directed behaviour after a combatant affiliated with its opponent was significantly lower than the rate after a combatant affiliated with other animals. Witnessing aggression increased arousal in bystanders, and reconciliation between the combatants was accompanied by reduced bystander arousal. The reduction was specific to contexts in which former opponents interacted. We suggest that bystanders recognized the functional significance of this conflict resolution mechanism when it occurred in their group.

Delay discounting task in pigs reveals response strategies related to dopamine metabolite.

We developed a novel delay discounting task to investigate outcome impulsivity in pigs. As impulsivity can affect aggression, and might also relate to proactive and reactive coping styles, eight proactive (HR) and eight reactive (LR) pigs identified in a manual restraint test ("Backtest", after Bolhuis et al., 2003) were weaned and mixed in four pens of four unfamiliar pigs, so that each pen had two HR and two LR pigs, and aggression was scored in the 9h after mixing. In the delay discounting task, each pig chose between two levers, one always delivering a small immediate reward, the other a large delayed reward with daily increasing delays, impulsive individuals being the ones discounting the value of the large reward quicker. Two novel strategies emerged: some pigs gradually switched their preference towards the small reward ('Switchers') as predicted, but others persistently preferred the large reward until they stopped making choices ('Omitters'). Outcome impulsivity itself was unrelated to these strategies, to urinary serotonin metabolite (5-HIAA) or dopamine metabolite (HVA) levels, aggression at weaning, or coping style. However, HVA was relatively higher in Omitters than Switchers, and positively correlated with behavioural measures of indecisiveness and frustration during choosing. The delay discounting task thus revealed two response strategies that seemed to be related to the activity of the dopamine system and might indicate a difference in execution, rather than outcome, impulsivity.

That Wall is Around My Heart: Family Centered Practice

The author uses a clinical case study, in which he works with a teenager and his adoptive parents to illustrate how placement and adoption decisions can provide physical safety while at the same time exacerbating and extending overlooked and destructive effects of child abuse. The case study highlights the continuing impact of childhood trauma on the interpersonal patterns of behavior within the family, whether biological, kinship, foster or adoptive. The tendency for patterns of aggression and reactivity to be repeated by the victim and his or her caregivers in a foster or adoptive home, and then to extend into the next generation, is an integral aspect of the cycle of child abuse and underscores a critical challenge for skilled and patient staff in family-based service programs.

Dear Enemies Elicit Lower Androgen Responses to Territorial Challenges than Unfamiliar Intruders in a Cichlid Fish

In many territorial species androgen hormones are known to increase in response to territorial intrusions as a way to adjust the expression of androgen-dependent behaviour to social challenges. The dear enemy effect has also been described in territorial species and posits that resident individuals show a more aggressive response to intrusions by strangers than by other territorial neighbours. Therefore, we hypothesized that the dear enemy effect may also modulate the androgen response to a territorial intrusion. Here we tested this hypothesis in male cichlid fish (Mozambique tilapia, Oreochromis mossambicus) using a paradigm of four repeated territorial intrusions, either by the same neighbour or by four different unfamiliar intruders. Neighbour intruders elicited lower aggression and a weaker androgen response than strangers on the first intrusion of the experiment. With repeated intrusions, the agonistic behaviour of the resident males against familiar intruders was similar to that displayed towards strangers. By the fourth intrusion the androgen response was significantly reduced and there was no longer a difference between the responses to the two types of intruders. These results suggest that the dear enemy effect modulates the androgen response to territorial intrusions and that repeated intrusions lead to a habituation of the androgen response.

Using the R-PAS' Aggressive Content Score For the Evaluation of Aggressive Behaviors in Children

The Rorschach Performance Assessment System (R-PAS) was developed in 2011 as analternative to the previous Comprehensive System. The goal was to improve the psychometrics,and particularly the validity, of this assessment method. The norms for children werequestionable in the Comprehensive system (e.g., outdated, low numbers of subjects) and validitystudies for children were sparse. One of the indicators included in the R-PAS system, theaggressive content indicator (AgC), is intended to reflect aggressive behavior, but few studieshave examined the validity of this indicator. This study examined the validity of AgC in asample of 32 children and adolescents receiving services at a residential treatment center.Subjects' AgC scores were analyzed in relation to demographics and diagnosis, as well as ratingsof aggression and conduct problems from the Behavioral Assessment System for Children-2(BASC-2) Parent and Teacher Reports. Correlations between the AgC score and BASC-2aggression and conduct problems scores were not statistically significant. None of thecorrelations between AgC score and a diagnosis of Conduct Disorder, Oppositional DefiantDisorder, Posttraumatic Stress Disorder, or Mood Disorders were significant either. Given thesmall sample size, null results may be a result of power concerns. The lack of significantcorrelations may however, indicate that operational definitions of aggression used in variousforms of measurement reflect different constructs.

¿Cómo se relaciona la ansiedad escolar con el rendimiento académico?

Se conoce poco sobre la relación existente entre la ansiedad escolar y el rendimiento académico de los alumnos. Este estudio analizó la relación entre ansiedad escolar y el rendimiento académico en una población de 520 estudiantes españoles de 12 a 18 años (M = 15.38, DE = 1.95). Los resultados revelaron que los estudiantes con alto rendimiento en castellano (lengua y literatura) presentaron puntuaciones significativamente más altas en ansiedad ante el fracaso y castigo escolar, ansiedad ante la agresión, ansiedad conductual y ansiedad psicofisiológica. Igualmente, los estudiantes con alto rendimiento en matemáticas presentaron puntuaciones significativamente más altas en ansiedad ante el fracaso y castigo escolar, ansiedad ante la agresión y ansiedad conductual. Además, los alumnos con éxito académico presentaron puntuaciones significativamente más altas en ansiedad ante el fracaso y castigo escolar, ansiedad conductual y ansiedad psicofisiológica. Sin embargo, los alumnos con fracaso escolar presentaron puntuaciones significativamente más altas en ansiedad ante la evaluación social. Finalmente, la ansiedad ante el fracaso y castigo escolar fue un predictor significativo del alto rendimiento en las asignaturas de castellano (lengua y literatura) y matemáticas, mientras que la ansiedad ante el fracaso y castigo escolar y la ansiedad ante la evaluación social fueron predictores significativos del éxito académico general. Así, los resultados indican un mayor rendimiento académico de los alumnos que presentan determinados temores escolares. Estos resultados podrían ser utilizados por profesores, psicólogos escolares y psicólogos clínicos como base empírica para desarrollar acciones preventivas y de intervención más eficaces del bajo rendimiento académico.

Conducta agresiva e inteligencia emocional en la adolescencia

Son escasos los estudios que analizan la relación entre conducta agresiva e inteligencia emocional. Este estudio examina la relación entre inteligencia emocional rasgo y los componentes motor (agresividad física y agresividad verbal), cognitivo (hostilidad) y afectivo/emocional (ira) de la conducta agresiva. El Trait Emotional Intelligence Questionnaire-Adolescents Short Form (TEIQue-ASF) y el Aggression Questionnaire Short version (AQ-S) fueron administrados a una muestra de 314 adolescentes (52.5% chicos) de 12 a 17 años. Los resultados indicaron que los adolescentes con altas puntuaciones en conducta agresiva física, verbal, hostilidad e ira presentaron puntuaciones significativamente más bajas en inteligencia emocional rasgo que sus iguales con puntuaciones bajas en conducta agresiva física, verbal, hostilidad e ira. Este patrón de resultados fue el mismo tanto para la muestra total como para chicos, chicas y los grupos de edad de 12-14 años y 15-17 años. Además, en la mayoría de los casos se hallaron tamaños del efecto grandes apoyando la relevancia empírica de estas diferencias.

Perfil sociodemográfico del feminicidio en España y su relación con las denuncias por violencia de pareja

Objetivo: Analizar las características asociadas al riesgo de feminicidio en España entre mujeres expuestas a la violencia de pareja o análogo y su posible asociación con las denuncias a los agresores. Métodos: Se realizó un estudio de casos y controles para el periodo 2010-2011. Los casos, 135 mujeres mayores de edad, asesinadas por su pareja o análogo durante dicho periodo, se identificaron a través de la página web de la Federación de Asociaciones de Mujeres Separadas y Divorciadas, y de los informes del Consejo General del Poder Judicial. Los controles, 185 mujeres expuestas a la violencia de pareja el último año, proceden de la Macroencuesta de Violencia de Género 2011. La asociación entre la denuncia y el riesgo de feminicidio se estimó mediante modelos de regresión logística multivariada. Resultados: No se encontró asociación entre denunciar al agresor y el riesgo de ser asesinada (odds ratio [OR]: 1,38; intervalo de confianza del 95% [IC95%]: 0,68-2,79). Las mujeres inmigrantes expuestas a la violencia de pareja registraron una mayor probabilidad de ser asesinadas (ref.: mujeres españolas; OR: 5,38; IC95%: 2,41-11,99). Esta asociación también se observó en las mujeres que vivían en zonas rurales (ref: zonas urbanas; OR: 2,94; IC95%: 1,36-6,38). Conclusiones: La denuncia judicial al agresor no parece modificar el riesgo de asesinato entre las mujeres expuestas a la violencia de pareja. Las medidas de protección a las mujeres deberían extremarse en las mujeres inmigrantes y las que viven en el medio rural.
